One is about raising tax revenue. The presentation implies that it is impossible to do so. That implausible suggestion rests on the common fallacy of inferring causation from correlation (or in this case the impossibility of causation from a lack of correlation).
It would be good to understand what's really going on. Is it an issue of avoidance/evasion ? Or is it that over this period whenever the US government raised revenue from one type of tax it somehow reduced another ?
The other point is about the circumstances in which government spending creates inflation. Inflation is what you get when more money chases the same amount of goods. Other things being equal, we might expect that
1) increasing the amount of money that people have to spend is inflationary wherever there are constraints (other than lack of demand) on increasing production.
2) robbing Peter to pay Paul is non-inflationary, printing money is always inflationary, and borrowing-to-spend is inflationary except to the extent that it increases savings rates.
Any thoughts ?
